DensDeck® Roof Boards

DensDeck® roof board is a highly mold resistant roof panel that consists of a moisture-resistant, non-combustible core of specially treated gypsum with glass mat facings. Approved by all leading roofing system manufacturers, Dens Deck delivers the highest performance ratings for fire, wind uplift, strength and moisture resistance.

DensDeck Prime® roof board offers all the features of the standard product, plus a non-asphaltic coating that enhances bonding in commercial single-ply and built-up roofing systems, including cold mastic and torch applied modified bitumen.  The green surface coating of Dens Deck Prime roof board makes it user-friendly by allowing a uniform spread of adhesives, which results in a stronger, more consistent bond.

DensDeck DuraGuard® roof board is an enhanced, glass-mat roof board with a low perm, integrated coating. The durable DuraGuard coating provides an ideal substrate for a wide variety of adhered roofing systems, including self-adhered, hot-mopped membranes, and torched asphaltic systems. It is ideal for metal roof systems and fluid-applied membranes.
